Molecules in the gas state move much faster than their liquid or solid states. Depending on the temperature and pressure, molecules can exist in three states: gas, liquid, o â¦ r solid. At high temperatures and low pressures, the gas state is favored.
I have been told that if you start using synthetic lube oil, you must continue. Going back to regular oil will damage the engine. That does not make sense to me.
As for synthetic oils, depends on the SynOil as to how long it will last. Even with reg. oil, 3k is a suggestion. If you change your oil quarterly (assuming you're an average driver who drives 40 miles in his/her commute to work), that's ok.
